Specification forming part ofl Letters Patent No.1222186. dated December 9, 1879; application filed February-1, 1879.

-\ To all whom it may concern:

Be it known that I, J osnPH GBBnLs, of St. J ohns Asylum,in the county of Kenton and State of Kentucky, have invented `certain new and useful Improvements in Machines for Twisting Wires; and I do hereby declare that the following is a full, clear, and exact description of the invention, which willv enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- `sponding parts in all the figures.

This invention relates to machines for twist- `ing wire; and it consists inthe construction and arrangement of parts of a machine adapt- Ved to twist triangular, square, or many-cornered (polygonal) wire, so as to form a spiraledged wire adapted to the manufacture of nails, and more especially that class of nails described in my Letters Patent of the United States No. 178,000, gran ted-to me on the 30th day of May, 1876.

` In` the drawings, A is the licor or platform of the machine, and B the frame. G is a shaft, journaled in boxes in one end of frame B, and provided with pulleys D, E, and F. In the other end of the frame is suspended the twisting and coiling mechanism, which consists of two circular disks, G H, united parallel to each other by parallel cross-pieces g h, provided with adjustable boxes or sleeves g' h' for the transverse shaft t', which is journaled in the said sleeves, and adjustable in itsrelation to the frame g h by means of a set-screw, g2, the inner end of which projects into a lon gi.- tudina-l groove in sleeve g', so that the position of this sleeve, with the shaft insertedl through it, may be adjusted by means of said set-screw i g2. Upon the middle ot the-adjustable shaft t is placed a langedidrnmy or cylinder, I, and

Y upon one of its projecting ends, on the outer side of the cross-piece h, is keyeda disk, K',

\ which will therefore be at right angles to disks G and H, and is so arranged as to project out 'responding to the shape ot' the wire.

vframe of the machine.

Disk G has a tubular shaft, f, journaled in the adjacent side ot' the frame B, and provided at'its other end with a chuck or flanged disk, e, between the dovetailed flanges d d of which is inserted the wedge-shaped twisting-head K, having a spirally-twisted perforation, 7c, cor- The opposite disk H has a central circular opening, through which is inserted one end of a short shaft, l, the other end of whichis boxed in the Shaft Z is prevented from projecting too far through the disk H by an annular flange, m, and is inserted through a stepped sleeve, t', upon which the contactdisk H' is mounted, as shown more clearly in the sectional view represented in Fig. 3.

N is a bifurcated spring-plate, securednpon the inner side of the frame, facing disk H', which is of larger diameter than disk G opposite, and the fork or arms of which said springplate straddle sleeve l', so as to impinge upon and press against the face of disk H'.

M is an adjustable standard, having a dovetailed horizontal slot, n, in its upper end, into which is inserted the removable drawing guide or head L, which is so arranged relative to the opposite rotating twisting-head K that their correspondingly-shaped perforations k k' shall be immediately opposite to and in a line with each other. `Standard M moves between parallel guides o o, and has a slot, p, in its base, through which passes aset-screw, g, by means of which the distance between the standard and the frame of the machine may readily be regulated.v n

Having in the foregoing described the construction of my machine, I shall now proceed to describe its operation.

The wire,which is placed upon a coil near the standard M, is inserted through the perforation in the drawing head or guide L, and then through the rotating twisting-head K and tubular shaft f until it reaches the drum I, to which it is attached. To facilitate the passage of the wire, disk G is, on its inner face, provided with rollers r r, between which the wire passes. A rotary motion is imparted to the disk G by means of the endless band G', and to disk H' by the band H2. By the bifurcated spring-plate N disk H" is brought .into contact with the periphery of disk K', which is rotated by the friction, revolving the shaftt and reel or Winding-drum I, by which the wire is drawn through the twisting-heads L and K, the spiral twist of the perforation in the latter allowing the twisted wire to pass through it readily. As the wire is twisted it is wound upon drum I, which, when full, may -be removed from the machine and an empty reel substituted. l

The pitch of the twist of the wire maybe regulated by regulating the distance between the two heads K and L by means of the adjustable standard M, and changing the rotating head K for one whose spiral perforation k corresponds to the greater or lesser pitch of the spiral to be drawn.

.It will be observed that by making the disk H' stationary the same result-wiz., the rotatin g of disk K', shaft i, and the reel I-would be accomplished; butin that case all the force requiredfor this operation would be supplied bythe two pulleys E and G and their. belt G'.

I have found by experience that it is more satisfactory, and productive of better results, to cause the rotation of disk K bythe rotationof disk H in the manner described, because in that case pulley F supplies, conjointly with E, -the force required to operate 'the machine, inasmuch as disk H' becomes an active operatin g element in the machine so far as the rotation of disk K' with its appurtenances is concerned.

It is also obvious that bevel-gears might be substituted for 'the'friction-diskslH' K'; but the advantage of these over gears consists in the adjustability of disk K', by making its shaft i adjustable in its bushings or boxes g' k'. By lengthening or shortening this shaft, which does not interrupt the contact of disks H' and K', 'the speed of the latter may be regulated, which could not be effected in like manner if gear-wheels weres'ubstituted for the friction-disks.

Having thus described my invention, I

claim and desire to secure by Letters-Pat- JOSEPH GBBELS.
